The roof of corrugated board : calculation and installation of their own hands

Roofing corrugated board allows you to build the roof of one of the cheapest ways.First, the roof of corrugated board mounted rather quickly. Secondly, for its devices, no additional construction materials other than standard heaters and all kinds of barriers is not required.

These factors cause a relatively small installation cost.But the most remarkable thing in the device of the roof of corrugated board is that it is quite possible to cover yourself.And the first thing that needs to be done in this way, so it is to learn how to calculate the necessary material.

How to calculate the material for the roof of corrugated

Calculation sheeting on the roof

fundamental factor in determining the amount of material needed is a roof area - namely in terms of its size calculation is carried out of the roof of corrugated board.

start counting with the necessary building materials of wood - usually profiled sheets laid on a special crate made from edging boards not less than 20mm thick.It is installed transversely spaced 200-300mm skates.Knowing the installation step bars and the length of the roof, you can easily calculate the amount of necessary forest in linear meters.

Go ahead and count the required number of insulation, vapor and Gidrobarer - all just here.The number of these materials is fully consistent with the area of ​​the roof, plus a small margin on the laps and issues.Typically, the percentage of this stock does not exceed 3.4% of the calculated figures.No need to save money on this - an unhealthy desire for savings will only lead to the fact that the design of the roof of corrugated board will be well enough to cope with the responsibilities assigned to it.Yes, and it will last much less.

With margin you must count himself profiled sheet - it fit with the overlap in the 100-150mm.Just round up the necessary material in a big way is wrong - as a percentage of the stock of numbers is characterized by 4-5% of the total roof area.It's the need to add on to the net roof area.

fasteners (screws to press the puck) exactly with a small error, too, can count - usually on the mount of trapezoidal sheet is required from 30 to 50 screws.

Thus, installation of the roof of corrugated board, we'll start with crates - assume that the supporting structure itself is already collected.The rafters are mounted virtually the same for all roofing materials, so distracted by them, we will not.

In the first phase of work on top of roof structure is laid gidrobarer - is reinforced cellophane tape designed for water, randomly leaked under the roofing material.Grinding Gidrobarer need to start with the lower edge of the roof - it is rolled out in the entire length of the roof and fastened to the rafters made of wood.If Gidrobarer width is not enough to cover the entire roof in one fell swoop, the next leaf is placed on the previous lap, the lap should not be less than 200-300.

gidrobarer When stowed, the following, which provides a roof of corrugated board technology - a device crates.Across the rafters steps 200-300 secured edging board - that it will serve as a basis for fixing the sheeting.With the same success it is possible or nailed to the rafters with nails or screws to fasten the long wood.

Pay particular attention to the roof ridge - there are separate boards lathing roof slopes should not be located close to each other.This gap ensures high-quality ventilation under-roof space.

is also necessary to ensure that small and departure boards crates beyond the roof - it's a kind of protection from the falling of the walls in the rain water flows.Departures should be approximately 200-250mm.

Well, the last stage of internal work, which includes roofing of corrugated board is the direct attachment of profiled sheets.This process will also need to start from the bottom of the roof - one edge of the overlying sheet of corrugated board should overlap the lower edge.Only in this way, providing an overlap between sheets within 100-150mm, can ensure complete sealing of the roofing of the profiled sheet.

Lying adjacent corrugated sheets must also be laid to overlap the previous one - is lapping step size is caused by the material of the wave.

Fastening profiled sheet metal is carried out with screws to press the puck directly into the top of the waves - they are installed in rows with a pitch of not more than 400mm.Adjacent to each other corrugated sheets are fixed next to one common screws.

And so is the roof of corrugated board with their own hands.But this is not the end of the entire roof installation - optional on the inside it is necessary to insulate.

How to insulate a roof of corrugated

Warming roofs of corrugated

This will require insulation type mineral wool and basalt slab and vapor barrier.

So, get down from the roof to the attic and start to work.Mineral insulation, whether rolls or sheets, is placed in the space between the rafters.For its fastening can use almost anything - it can be glued, screwed screws with a wide washer and even fix the taut thread.How do you fix it, it's up to you personally, it is important to mount to fulfill its function and not to compress the seal.Remember that prevents the penetration of cold itself is not wool, and the air trapped inside it.

Next wool pulled over the vapor barrier - the principle is the same as when laying Gidrobarer.Why is it needed?The fact that the moisture contained in the air, can reduce the thermal insulation characteristics of the mineral wool - the more it absorbs moisture, the less it will be able to retain heat.To prevent the ingress of moisture into the insulation, use of steam and Gidrobarer.

Particular attention should be paid to the creation of so-called cold triangle at the top of the roof - it is not necessary to insulate the space located at a distance of 300-400mm from the roof ridge.This cool triangle will improve the air circulation in the attic, and at the same time provide high-quality ventilation inside of the roof.

That's basically all you need to know about how to make a roof of corrugated board.Complicated is nothing, strictly adhere to all the main installation technology.A roof size and amount of work does not need to be afraid.

If you are afraid, that left without shelter house can be affected by rain, the work can be done gradually - opened part of the roof and immediately made it, then the other part.The roof of corrugated board makes it easy to carry out a sequence of works.
